Certified for safety and built for quiet, reliable operation, it’s a trusted choice for professionals demanding performance and longevity. ## Description Siemens Definite Purpose (DP) Contactors The DP Contactor was developed for applications such as HVAC, refrigeration, fans, blowers and welders for OEMS and manufacturers of machinery. However, the market for DP contactors has grown to include many more commercial, construction and industrial applications. These reliable contactors are available up to 90 amps and in 1- 2- or 3-pole configurations at coil voltages 24-480V. The Class 42 family includes 2- and 3-pole units from 30A to 90A. These devices also accept auxiliary contacts and coils can be replaced. The Class 42 include screw terminals for the 30A and box lugs for the 40A and higher versions. A durable back plate is common with the series. The Class 42 also offers quiet operation, weld resistant silver Cadmium Oxide contacts and has a visible contact position window. The Class F coil insulation gives the Class 45 a greater thermal stability in operation.

Actual coil voltages will vary based on product description Review: Be carefull to check the contactor coil pull in voltage - I bought two of these for some AC units at work. The picture shows the 48VAC model but I ended up with the 208VAC model. I simply did not pay attention to the title and instead focused in on the products model number in the sample picture. My fault in a way but since there are no options on the item page to select different coil voltage models I think it's bad form for them to use the picture of the most common model when they should use the picture of the one they are selling. ## Features - 3-Pole, 40 Amp, 208-240V 60Hz, 190-220V 50Hz - Snap-on auxiliary contacts and replacement coils available - Durable metal back plate for universal mounting - Screw terminals and quick connects for easy electrical connections - cRUus, ARI 780 & 790, UL File E14900 ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 4 Reviews | ## Images ![Siemens 42CF35AG Definite Purpose Contactor, 3-Pole, 40 Amp, 208-240V AC Coil Voltage - Image 1](https://m.media-amazon.com/images/I/61p3QLPiT7L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Be carefull to check the contactor coil pull in voltage *by R***G on May 5, 2021* I bought two of these for some AC units at work.
